Police say the man suffered trauma to his head and was rushed to hospital by ambulance.

Waterloo Regional Police Staff Sgt. Robert Munro tells CTV News that they are not looking for any suspects and no weapons were involved in the incident.

The University of Waterloo says none of the people involving in the attack are current students at the school so they’re leaving the matter up to police to investigate.

“Right now detectives are interviewing anyone who was close by, who may have an idea of what happened.” Munro says. Police are still trying to determine if the suspects’ intent was malicious or the injuries happened as a result of misadventure.

Anyone who may have been in the area at the time of incident is urged to call police at 519-653-7700 ext. 6353 or Crimestoppers at 1-800-222-8477.
